If you scan your channels you will find out if it is digital. Say for instance you get channels 2-1, 16-3, 12-2, 12-3, then your TV is digital. Now if all your channels have no dashes and your channels come up 2, 12, 9, 16, and so on then you have an analog TV. Since this is a walmart brand there is not any online support that I can see. If you bought this a few years ago then again your tv is more than likely analog.

Val,
It's sent via Pando and you should get a link to it in your mail. To open it you'll need Pando, it's a free download if you don't already have it... The hyper module on that has about 10 caps that are common in that failure. If you need anything off board don't hesitate to ask.
